Your approach to solve SC questions requires the below steps:
1. Find errors in the underlined portion
2. Look for other options where these errors have been corrected
3. Check whether other things are constant while the errors are corrected
Notice that in the given question
mialanknox
The 2010 American Medical Association's estimate of the number of primary care physicians in the United States
needs revision because the statistic overestimates the number of practicing physicians by including some retired physicians and others who have left the workforce.
A. needs revision because the statistic overestimates the number of practicing physicians
B. need revision due to the overestimate of the number of practicing physicians
C. needs revision because the statistics overestimate the number of practicing physicians
D. needs revision due to the fact that the statistic overestimates the number of practicing physicians
E. need revision because the statistics overestimate the number of practicing physicians
The 2010 American Medical Association's
estimate is the subject which is singular. Therefore the verb
needs is in its correct form.
Secondly, we also have a dependent clause after because...
the statistic is our subject which is singular.
Overestimates has been used as a verb here and it is in its correct form.
This means that we haven't found a single error in the underlined piece.
Therefore, A is the answer!__________________________________________________________________________________________________________
